Push It Out
Source Institutions
In this physics related activity which requires adult supervision, learners make their own powerful water rocket and, with it, explore Newton's Third Law of Motion.
A Feast for Yeast
Source Institutions
In this activity on page 6 of the PDF (Get Cooking With Chemistry), learners investigate yeast. Learners prepare an experiment to observe what yeast cells like to eat.
Weight For It!
Source Institutions
In this activity about weights and balances, learners create their own balance using paper cups. Then, learners explore how to compare the relative mass of objects.
Cool It!
Source Institutions
In this fun hands-on activity, learners use simple materials to investigate evaporation. How can the evaporation of water on a hot day be used to cool an object? Find out the experimental way!
Hot Stuff!: Investigation #2
Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.
Hang Time
Source Institutions
In this physics activity, learners will build their own parachutes out of tissue paper. They will explore the effects of weight, height, and design on the parachutes' speed and stability.
Changing Body Positions: How Does the Circulatory System Adjust?
Source Institutions
In this activity about how the body regulates blood pressure (page 117 of the PDF), learners make and compare measurements of heart rate and blood pressure from three body positions: sitting, standing
Treasures in the Rough
Source Institutions
In this archaeology activity, learners make observations and conduct an experiment to demonstrate the effect saltwater has on artifacts.
Regolith Formation
Source Institutions
In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.
What's So Special about Water: Solubility and Density
Source Institutions
In this activity about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.
Gravity and Muscles
Source Institutions
In this activity about center of gravity (page 23 of PDF), learners investigate how the body adjusts to the force of gravity to remain balanced.
¡Ciencia efervescente y espumosa!
Source Institutions
En esta actividad la tira cómica muestra a los participantes como pueden hacer un experimento simple para ver cuales líquidos son ácidos.
Breathing Yeasties
Source Institutions
In this life science activity (page 8 of the PDF), learners explore the carbon cycle by mixing yeast, sugar and water.
Mapping the Homunculus
Source Institutions
In this activity, learners will explore how the human brain interprets environmental stimuli.
Inverted Bottles
Source Institutions
In this activity, learners investigate convection by using food coloring and water of different temperatures.
There's Always Room For JELL-O
Source Institutions
In this activity, learners cut wells in JELL-O© and load the wells with different detergent solutions.
ANTacid: Indicator Paper on an Anthill
Source Institutions
In this activity, learners make acid/base indicator paper, place the indicator paper on an anthill, disturb a bunch of ants, and then observe what happens!
Canned Heat
Source Institutions
In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.
Crunch and Munch Lab
Source Institutions
In this activity, learners use three types of cheesy snacks--cheese balls, cheese puffs, and Cheetos--to learn about polymers.
Clippy Island: An Investigation into Natural Selection
Source Institutions
In this activity, leaners will observe the process of natural selection on a population of birds called 'Springbeaks' over four seasons of breeding on an isolated environment called 'Clippy Island.' L
